How do you program a new Transponder Key (Door Key) for a 2005 STS .
I can't find this in my owners manual
I can get a key on Ebay for about $15 the dealer wants $50
I do not have an ignition switch (only the door will take a key)

A 2005 STS key is not a transponder key. What does all the work is the key fob; sometimes called the key. The fob unlocks the doors, opens the trunk, and allows you to start and drive the car.

I have 2006 Cadillac STS and had a key made at the locksmith. It's for my fob upgrade but the key works in both the glove box and the pass through, but not the door. The one that came with the car works all three. What can I do to get it to work all three?
